Ultra-Efficient Products, Invader Mark III
Ultralight Aircraft Magazine - The Mark III invader was originally designed by Nick Leighty and Rick Berstling in 1982, as a part 103 legal ultralight aircraft. It uses a welded aluminum tube construction in the fuselage, mated to a double sleeved aluminum irrigation pipe extending out to the the V tail. The wings are constructed from wood using foam ribs covered in standard aircraft covering materials.
Early model Mark III Ivaders for two axis control, with all of the controls working off of the control stick, in later models rudder pedals were added. The aircraft is a pusher, in a mid-wing configuration, with a tricycle gear, and a steerable nose wheel.
The Mark III invader can be powered by engines ranging from 14 to 36 hp. These include the 14 hp single cylinder yeah my engine on up through the Rotax 377 and 447.
Problems were reported with separation of the ribs from the main spar.

Ultralight Aircraft Magazine - Welcome to the Ultralight Aircraft News our goal is to cover as many aircraft expositions that host aircraft described as ultralight aircraft, light sport aircraft, experimental light sport aircraft, amateur built aircraft, ELSA or homebuilt aircraft that fit into the definition of ultralight aircraft in Canada or light sport aircraft, or experimental amateurbuilt light sport aircraft in the United States.
These include three axis control aircraft, weight shift control aircraft, more commonly known as trikes, powered parachutes, helicopters, gyrocopters and powered para-gliders that meet the light sport or ultralight aircraft definition.
Airshows and aircraft expositions that we cover include, the Deland Sport Aviation Showcase, U.S. Sport Aviation Expo, Deland Sport Aviation Showcase, E.A.A.'s Sun N Fun, E.A.A.'s Airventure, the Midwest LSA Show, Copperstate, UPAC Convention and Aero Friedrichshafen in Germany. We try to regularly attend regional shows like the Arlington Fly-In, and Rocky Mountain Fly-In.
